Screen size and throw distance

You can adjust the projection size with 1.2x zoom lens. Calculate and define the throw distance as follows.

Calculation methods
NOTE:
• See "Screen size and throw distance for 16:9/4:3 aspect ratio" on page 54.
• Do not use the projector at a raised or a horizontally tilted position as it may cause
malfunction of the projector.
• You can tilt the projector body approximately ± 30° vertically. Overtilting may result in
shortening the component's life.
• For the best quality of the projection image, install a screen where sun light or room light
does not shine directly onto the screen. Close window shades or curtains to block the lights.
